I have a friend on an Android phone. Long story short, he needs to start having better battery life.
I know that having custom kernals allows for overclocking, but all he needs is the underclocking.
If I root his phone, set his profiles up without a custom kermal, would that still help his battery when setting up his max and min settings?

Yes, SetCPU should lower battery consumption. Configure your screen off profile to underclock the CPU when the screen is shut off. You will need to have your phone rooted for this.
you should notice a significant gain of battery life. This thread should provide some more information.

Not necessarily. Underclocking can sometimes use more battery when your phone is active. With less power the process takes more time to activate and that means more juice. Search in threads for "underclock", you'll find more infos on the subject.
Hey guys, what I'm asking is does he specifically need a kernal? Or, can he rootv and JUST use Set CPU?
Sent from my HTC Glacier using XDA App
Imo, he would get better uc/oc results with a modified kernel.

to answer you, no he can use just root and setCPU.
custom kernels help alot. but its not required.
Firstly: What phone does your friend have? Make and model, Android OS version, etc.
Secondly: If your friend wants to seriously underclock his phone, tell him to look into low-voltage kernels. He would probably just be better off with a custom ROM and such. If he has a question, tell him to type it into Google and the answer will most likely pop up.
Thirdly: SetCPU will always help with performance/battery consumption, you just have to be rooted for it to work and learn how to set up profiles properly. Once again, Google is your friend.

Anyone here try setcpu on your Galaxy S 4G?
I'm sure there is some "new and improved software" reason to not need it, but I figured I would try it to see if I could improve battery life in some way.
I'm still tinkering with the settings, but I think I have noticed a slight improvement. If you try it, don't set your screen-off speed to any lower than 400mhz. If you do your phone will slow to an unimaginable crawl, sometimes only to be recovered from with a reboot/battery pull.
Sent from my rooted Galaxy S 4G
You can use it but until there are custom kernels that allow you to underclock or overclock its gonna be a lost cause imo. At this point its only good for changing governors and possibly screen off profiles and things like that

It already hauls once I removed bloatware, my system is pretty "bare bone" now, and it's FAASSSTTT.
That being said, one of the main reasons I upgraded to this phone from my modded HTC HD2 was the battery life was horrible on that phone (comparible to an evo 4g as per many side by side tests with a friend who had a new one).
Battery on this phone is GARBAGE, basically the SAME battery life, maybe only slightly better if at all....
I thought technology was supposed to be improving. I mean I abuse the phone, It's my sole entertainment while I'm at work (I work at a call center). I'm doing things on it 24/7.
But I figured it would perform better than a non-native android phone, modded to run android, that's two years old.. (htc hd2)

TegraK seems to work. It's an "on demand, on the fly" patch that isn't persistent.
I see improvements in benchmarks and reads/writes. So, it seems to work. Every time you reboot though, you have to reset it.

Could some give me a quick rundown on undervolting a kernel. I'm using faux's 0.4.2 oc/uv cm7 kernel. From my understanding its already undervolted but I'm confused about whether I should/can adjust those settings for better results or if I should leave them alone.
Info greatly appreciated.

Each chip is built differently, so you have to experiment on that yourself. That kernel may already be undervolted but it may not be right for you. I say adjust until you hit instability and then go from there.

Yes anytime you make you phone do something it didn't do from the factory there is a chance you could damage your device..its thx to all the great devs and people that test that make it easier and less likely also the more you read and understand what it is you are actually doing to the device helps alot!
If you have a kernel able to be overclocked/undervolted yes just use set CPU to adjust the settings.
All chips are different just cause a specific setting is working for someone else means it will work the same for you!
That being said I use:
Trigger 8/22 rom with faux123'a 0.4.2 kernel.
My settings:
Max-1408mhz
Min-389mhz
And have 1.1 GHz down to 389 mhz undervolted by 50 and no undervolt above 1.1
also have different profiles set for screen off and in call..
Good luck how this helps..

Thank you for such a detailed explanation! I'll be more weary of fooling around with settings. I'll probably set mine similar to yours.
Thanks everyone. I understood that setcpu would be used for the changes I was more wondering what the changes would do. Like undervolting by 50 for instance, what does that give as far as battery life? Im a moderate to heavy user and I only get roughly 8 hours off the charger before it needs to be back on, great signal all day too.
I suppose I'll just have to tinker with it till I get crashes then adjust from there.

How do u get the undervoltage adjustment? i have set cpu and when i try the voltage button on set cpu, i got forced closed. Thanks in advance.
Sounds like a bad install, try uninstalling setcpu then re-installing it or fix permissions in CWM or terminal
su
fix permissions
Used to have that issue too. Try the setcpu available here on the forums, I think that's the one the worked for me.

Well I'll start with what I think I'd think to be easy and i'm just not seeing it. OC daemon for aosp. I've seen it built in, but how to add to already installed ROM? Now another question. Even with pinky undervolt and the radio that I was recommended for the ROM blackice, I'm getting horrible better life
compared to when I had sense 3. Any idea on that? Thanks to any help someone can throw out.
Sent from my Desire HD using XDA App
For the OC Daemon, I would try searching the forums for a thread dedicated to it. If they have an installable .apk for it, you would simply download that and install like any other app. If its a system app, you would have to mount /system with say ES file explorer, copy it to /system/app and then assign the proper permissions.
My questions is if there is a way to confirm that undervolts are being applied. In the blackice thread some people were saying the included tool might not be applying them correctly. Thought id make a few posts here though so I could post in the actual thread lol.

OC/UV Beater will show you what your voltages are currently set to:

Correct me if I'm wrong, but if you're referring to the OC daemon in ARHD I think that's written for his CPU scheduler. If you're on AOSP I would recommend SetCPU
Well with the OC daemon question, I have seen people build it into cm based roms. So I was just thinking, if they can do it that way, why not in a preinstalled ROM.

Thanks for the suggestion. After I asked I found out systune included in the rom showed the values and they are being applied.
Correct if I'm wrong but setcpu will anything that ocdaemon can do. I would just use that or choose a rom with it cooked in.
Setcpu just follows governors. the OC daemon uses governors but also has set clock and governor for screen off and on, therefore, saving battery life. Also better performance.

Works fine here.
I'd just like to know your opinions on it, does it save battery, performance? What app do you use? Btw, i know that there is no best app, i am just asking for an opinion so dont flame...lol
It works well for me. Seems to extend battery life. I use oc/uv beater or incredicontrol depending on the ROM.
You have to try and find the lowest voltage where the ROM is still stable under load.
Undervolting saves battery by the pure fact that your CPU gets less power dissipation. How much battery - depends on the setup, the CPU isn't the only power-hungry device in the system. If you use a lot of screen, by reading, for example - undervolting won't help you much. On the other hand, it'll help your standby time, it'll somewhat reduce the heating of the phone and save the battery this way, etc.
OC/UV beater for me, too.
I'll try out oc uv beater. Is it on Google play? Can't seem to find it, otherwise I'll just get it off of a rom or something

No reason to. It was meant to control kernel options, using the clock and voltage scalers built into kernels, and not to set the options in runtime like SetCPU.

I just started using Voltage Control. It seems pretty good. I heard some good things about setCPU and some bad. That's why I started this thread. I wanna know the difference between all of them cuz there's so many lol. Like, I don't know if some are the same app with just different names or if they are made and coded differently to handle things differenly.
I used setcpu before anything similar was integrated into ROMs, I bought it.after a while and haven't used it since. I don't overclock or anything because I don't use my phone for games, mainly media.

I'd say so. But I use to have an aria which was a 600MHz single core. I clocked it up to 806MHz. And that was considered fast 2 years ago!
With a dual core at 1.5GHz, I'd say it's nothing more than a battery drain if you aren't gaming. What I do however, is underclock my hox while the screen is off.

Using profiles? What do you underclock it to? Whenever I would do that I would set up a profile for screen off and use max 384 and min 192 or 384 but that may be a little extreme.

Same here....
I agree though, that there is rarely a real "need" to overclock unless you feel the rom is slow or you are an avid gamer..
I use SetCPU because it was the first app I came across, but I've stuck with it for the small features. I like being able to set notifications when individual profiles become active (useful for games), and seeing the "Time in State" pie chart lets me know if my CPU is being fussy when idling. Sure, other apps may have more features, but there's literally no reason for me to look for a new one
Rom toolbox pro works fantastic!

Using No-Frills, not a whole lot of features but the most lightweight app I have found for handling OC, I like SetCPU but I would get wakelocks it seemed using profiles, so didn't add much benefit IMO.
